Dear all. Under current climate conditions plant diseases and pests, (mammalians, weeds, insect pests, nematodes and plant pathogens like fungi, viruses, bacteria) can cause considerably yield losses and damages of crops. Climate change will likely lead to increase the frequency, intensity, spatial extent, duration and timing of weather and climate extremes. Does anyone have any information about the impacts of extreme weather events on diseases and pests of alfalfa and clover? We reviewed the possible impacts of weather extremes on pests (weeds, insect pests and plant pathogens) of hop by analyzing scientific literature published since 1945, concerning the knowledge about the influences of extreme weather on incidence of these pests. Our literature survey started on February 2013 and is continued monthly. In the databases “Web of Science” and “Scopus” the mode “Advanced Research” was used and a combination of “extreme weather terms + plant terms + plant pest terms” was entered. We have found anything until today.
Hi, The wheather conditions caused outbreak of pests and diseaes. For example lmpact of rising temparature caused outbreak of mites and the impact on performance nature enemies.
Thank you very much Samaneh for your answer. But, sorry, that's a very general answer. It is known, that climate change and also extreme weather can cause outbreak of some pests and their enemies also. Other pests may be diminshed. The question is: How extreme weather events like heat, drought, storm, heavy down poors, hail, flooding will influence the special diseases of alfalfa and clover and the special plant protection measures (chemical and biological) in clover and alfalfa. We found nothing in literature but need more information for risk assessment. Kind Regards, Petra
